Originally released in the 1960s, the Top Time's graphic dial and bright colours were designed to appeal to a young and active demographic. Fifty years on, it looks as sharp as ever. Nicknamed the "Zorro dial" by collectors, it stands out for the unusual decimal scale that divides the minute into one-hundredths rather than the conventional 60 seconds – a more practical division when calculating times or prices, for example. Inside the 41mm steel case ticks the Breitling Calibre 23 Chronograph movement that provides up to 48 hours of power reserve. Its precision timekeeping has earned it chronometer-grade certification from the COSC. Red hands and dot markers glow in the dark thanks to a coating of Super-LumiNova®. Interestingly, this Top Time is the first Breitling watch to be issued with a tamper-proof blockchain digital passport. A limited edition of 2,000 pieces.
